WHEELED PLOW.

SPECIFICATION forming part of Letters Patent No. 616,984, dated January 3, 1899. I

Application filed January 31, 1398. Serial No. 66 8,661. (No model.)

T0 at whom it may concern.-

Be it. known that I, NIELS O. STARKS, a citizen of the United States, residing at Madison, in the county of Dane and State of WVisconsin, have invented certain new and useful Improvements in Wheeled Plows, of which the following is a specification.

My present invention pertains to improvements in wheeled plows, the advantages and construction of which will be hereinafter set forth, reference being had to the annexed drawings, wherein Figure 1 is a top plan view of the machine; Fig. 2, a side elevation; Figs. 3 and 4, side elevations of certain portions of the machine, the main land-wheel being omitted or shown only in dotted lines; Fig. 5, a perspective view of certain details of construction, and Fig. 6 a side elevation showing'the relation of certain parts under varying conditions.

One object of the present invention is to provide means for raising and lowering the plow and to so construct said parts or means that the plow may be elevated when it strikes an obstruction.

A further object is to provide suitable means for guiding the front furrow-wheel,

whereby the machine may be manipulated and turned with facility.

A still further object is to provide suitable spring mechanism for forcing or drawing the plow into the ground.

Other advantages are present and will present themselves inthe'following description and claims. 5

The main frame of the machine consists, essentially, of the bars 1 and 2, bent to form, as shown in Fig. 1, and connected at their rear ends to a casting 3, which is so shaped as to form an upright bearing for the vertical stem 4 of the rear axle 5, upon which is mounted the rear furrow-wheel (5. The forward ends of said bars 1 and 2 are directly attached to casting 7, which, asin the case of casting 3, is formed with a vertically-disposed opening or bearing in which is mounted a cranked arm 8, said arm having secured to its lower end a short stud-axle for the front furrow-wheel 9. The bearing 10 for axle 11 of the land-wheel 12-is mounted between two bars 13 and 14, both being bolted to the main bar 1 and the latter, 14, extended forward and connected to the block or head 15. In this head there is journaled a post 16, having secured to its upper end an arm 17, extending to both sides of its center. Upon that end of the arm 17 next to the furrow-wheel 9 there is mounted an adjustable seat 18, to which is attached the pole 19, while the opposite end of the arm is pivotally connected bya bar'20 with the cranked arm 8, as clearly indicated in Figs. 1 and 2. Through these connections it will be seen that as the pole is turned the front furrow-wheel will also be turned to a similar degree. By thus constructing the parts the pivot-point of the pole and point of attachment of the evener or trees to the plowbeam are approximately in alinement.

It is manifest that a wheel and chain connection or gearing may be employed instead of the construction just set forth.

The usual or any approved form of device may-be employed for raising or lowering the forward portion of the frame upon the vertical member of the cranked arm 8-such, for instance, as the lever 21 and link 22. Similar devices are employed in connection with I the land-wheel '12, so it will be seen that the frame may be raised or lowered, as desired.

The beam 23 carries at its forward end a clevis 24 and has attached to its lower rear end the plow 25. The beam has secured to it two brackets or castings 26 and 27, in the first of which is journaled a bail 28, said bail being formed as an integral part of or rigidly affixed to the axle 11. As shown in Fig. 1, the bail is journaled in brackets secured to the side bars 1 and 2. Abail 29 is journaled in the bracket or casting 27, the'ends of the bail being seated in bearings formed in de pending brackets 30 and 31, secured to the bars 1 and 2.

A link or eye 32, Figs. 3 and 4, is pivotally secured to the forward part of the frame and passes around the beam, a pin 33, passing through the beam, determining their relative position when the beam is lowered, as in Fig. 4. At the rear end of the frame there is provided a bearing 34, in which is mounted a being drawn back as far as possible.

shaft 35, Fig. 5, said shaft having formed or secured upon one end an arm 36, while the opposite end is provided with a squared portion 37 and a threaded end. A lever 38 is loosely mounted upon the projecting end of the shaft 35, while secured upon the squared portion 37 is a block 39, provided with a recess 40, formed by the long lip 41 and the relatively short lip 42. The lever 38 carries a spring-actuated pawl or detent 43, designed under certain conditions to enter the recess of the block, and thus lock the lever and shaft 35 together. Arm 36 is pivoted to a link 44, which in turn is pivotally connected to the rear of the bracket 27 or directly to the plow-beam, as may be desired. Said link 44 extends up past its pivotal connection with the arm 36 and has secured in a lateral projection 36, at its upper end, an eye 45. A set-screw 46 is also mounted in the upper portion of the extension of the link 44, the screw serving to adjust the relation of the parts, as will presently appear.

Secured to the plow-beam is an arm 47, and between the rear end of said arm and eye there is secured a coiled spring 48. Pivoted upon the bracket or hearing 27 is a latch49, provided with a nose 50, the latch extending .into link 44, Figs. 1 and 2, and coming in contact with the upper beveled end of arm 36.

A suitable seat 51 and foot-rests 52, 53, and 54 are provided, the rest 54 being attached directly to the beam, as shown. A heavy coiled spring 55 extends forwardly from the lower rear portion of the frame and is connected to the rest 54.

To maintain the rear wheel in place, an arm 56 is secured upon the upper end of stem or post 4, 'a spring-latch 57 engaging with the end of the arm, the latch in turn being controlled by rod 58 and foot-lever 59.

lVith the parts in the position indicated in Figs. 1, 2, and 3 the plow is elevated and the beam occupies its highest position as well as If it now be desired to lower the plow, the operator draws the lever 38 forward, the pivoted pawl 43 being in engagement with block 39, and consequently rotating shaft 35 and with it carrying arm 36 forward and downward, the latch 49 meanwhile having been elevated, so as to permit its nose to ride over the upper end of arm 36. As the arm 36 moves forward and downward it will cause the link 44 also to move forward and downward, the parts moving from the position indicated in Fig. 3 to that shown in Fig. 4. Arm 36 and link 44 form a toggle which serves to force the beam forward and downward, the bails 28 and 29 permitting the beam to be lowered and moved bodily forward. Spring 48 also tends to draw the toggle into its straightened position and in so doing serves to force the plow into the soil and to hold it there. When the parts are in the position shown in Fig. 4, the end of screw 46 bears upon arm 36 and serves to prevent the pivotal points of the toggles from coming into exact alinement. Spring is put under tension as the beam is moved forward and downward, and when the beam is lowered to its greatest extent said spring also serves to hold it in this position. As the lever 38 comes to its forward position the tail of latch 43 comes into contact with a projecting arm 60, Figs. 1, 3, and 6, and the nose of the latch is withdrawn from the recess 40. The position which the parts occupy is indicated in full lines in Fig. 6. If, however, the operator should raise the lever, the latch would immediately engage with the block, locking the parts together, whereupon upon a further rearward movement of the lever the beam and plow would be elevated.

It will be noted, as above pointed out, that when the plow is lowered into its working position lever 38 is wholly disconnected from the working parts, and should the plow strike an obstruction it would rise up, breaking the line of the toggle, but leaving the lever 38 down, the relation of the parts being shown in the full and dotted lines of Fig. 6. From the relation of the springs, as shown, spring 55 serves when the plow is down to hold it down; but when the plow encounters an 0bstruotion and is raised to a certain extent the spring then acts to elevate it to its highest degree. If after having struck an obstruction and the plow is elevated the operator desires to lower" the plow, all that is necessary is to bring the lever back until the latch e11- gages the block, when the parts will be locked together ready for another forward movement.

The arrangement of the parts whereby the plow may be automatically raised without having the lever fly back past the operator is of marked advantage for obvious reasons.

Inasmuch as the beam is supported by bails which are journaled in the frame, the plow must of necessity always occupy a horizontal position.

By adjusting the screw 46 the toggle-joint may be regulated, and by tightening the spring the plow will be drawn more firmly into the ground. By loosening the spring the plow will more readily jump up when it strikes an obstruction, and by so doing will relieve the whole structure, as well as, the team, from what might possibly be a severe shock in bringing up solidly.

It is manifest that other arrangements and locations of springs will suggest themselves for drawing the plow into the ground, while at the same time permitting it to rise freely when encountering an obstruction. So, too, either of the springs may be omitted and the operation of the parts will be the sameybut of course the single spring would have to do the work of both and would not work so advantageously.

Instead of journaling the bails in the brack ets, as shown, it is manifest that they could ICO ICS

be journaled directly in the frame, and the claims are to be read in light'of this statement.
